Nostoc \Nos"toc\, prop. n. [F.] (Bot.)
A genus of algae. The plants are composed of moniliform cells
imbedded in a gelatinous substance.
Note: Nostoc commune is found on the ground, and is
ordinarily not seen; but after a rain it swells up into
a conspicuous jellylike mass, which was formerly
supposed to have fallen from the sky, whence the
popular names, fallen star and star jelly. Also
called witches' butter.
From WordNet (r) 3.0 (2006) :
n 1: found in moist places as rounded jellylike colonies
